The binding energy of the exciton—neutral acceptor complex is calculated by means of an atomic‐like variational wave function, suitable for not too large electron‐to‐hole mass ratios σ = m e * / m h * . The results obtained with a 46‐term trial function do not disagree with previous deductions stating that there is a σ‐region of instability. Further, the empiric “Haynes rule” is not well verified in the limited region (σ ≦ 0.431), where the stability can be achieved by means of our trial function. The computed energies are in good agreement with the experimental data relative to GaAs.
